BackgroundLittle evidence exists studying the benefits of pre-hospital trauma team activation. Our study measured the impact of pre-hospital trauma team activation on 24-h survival. Our secondary objectives assessed the effects of pre-hospital trauma team activation on time to emergency procedure, computed tomography, blood transfusion, and critical administration threshold, as well as emergency department length of stay.MethodsWe conducted a 40-month health records review on all trauma team activations at The Ottawa Hospital, a Level 1 Trauma Center. Outcomes were compared between pre-hospital and in-hospital trauma team activations. We used logistic and linear regression models to assess outcomes, while controlling for injury severity score, age, systolic blood pressure, and anti-coagulation use. A P value < 0.05 was considered statistically significant. A sensitivity analysis was also used to validate the primary outcome results.ResultsOf the 1013 trauma team activations occurring during the study period, 762 patients were included. The mean age (41.3 vs. 43.8) and percentage of males (79.4% vs. 77.5%) for pre-hospital activations were similar to their counterparts. Pre-hospital activations did not have a statistically significant effect on 24-h mortality (14.4% vs. 4.5%; P = 0.30). However, pre-hospital activations did demonstrate a statistically significant reduction in time (minutes) to emergency procedure (18.0 vs. 27.0; P < 0.001), computed tomography (37.0 vs 42.0; P = 0.009), and blood transfusion (14.0 vs. 28.0; P < 0.001), as well as emergency department length of stay (101.0 vs. 171.0; P < 0.001).ConclusionWhen controlling for key covariates, pre-hospital trauma team activation did not have a significant effect on 24-h mortality, but did result in a significant reduction in time to emergency procedure, computed tomography, and blood transfusion, as well as emergency department length of stay. Our study demonstrates that pre-hospital trauma team activation can expedite patient intervention and disposition.© 2023.
